FRED. S. ELWVELL, OF DETROIT, MICHIGAN, ASSIGNOR TO THE DETROIT PAPER NOVELTY COMPANY, OF SAME PLACE.

MACHINE FOR MAKING PAPER VESSELS.

SPECIFICATION forming part of Letters Patent No. 416,585, dated December 3, 1889.

Application filed May 28, 1888- To all whom it may concern.-

Be it known that I, FRED. S. ELWELL, a citiaen of the United States, residing at Detroit, in the county of Vayne and State of M ichigan, have invented certain new and useful Improvements in Machines for Making Paper Vessels; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in no the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a device for making paper vessels, and particularly that class of vessels known as berry pails or buckets, being used by merchants as a cheap package, taking the place of paper sacks, being much more durable, and as these vessels are made from a much, heavier grade of paper, berries and tender fruits are not injured or soiled as when placed in the common paper bags, thus making a much better package.

The object of this invention is to enable the making of such vessels at a price that will enable the manufacturer to place them onthe market at a price as lower nearly as low as that asked for the common paper bag; and my invention consists in the combination of certain elements, as will be hereinafter fully set forth, and pointed out particularly in the claims. p

In the accompanying drawings, forming a part of the specification, Figure 1 is an isometrical view of my invention. Fig. 2 is an enlarged cross-section taken on dotted line X X of Fig. 1. Fig. 3 is an enlarged view of one of the formers, showing by dotted lines the clamping-bar in a locked position. .Fig. 4 is a plan of a blank from which the body of the vessel is made. Fig. 5 is an upright former, in elevation, showing a vessel thereon in section. Fig. 6 is avertical central section of a vessel, showing the manner of attaching the bail thereto.

In the drawings, A represents a platform or table having in its upper face the channels or tracks h. On said platform is mounted a traveling frame consisting of the base 0, car- Serial No. 275,278. (No model.)

rying the wheels TV, which travel in the channels h of the platform.

92 n are uprights mounted on the base O, carrying at their upper ends the supportingrail S. Attached to this rail is a series of horizontally-projecting arms or spindles S, their outer ends carrying the vessel-formers F, which are conicallyshaped,to give the vessels a flaring shape, being of greater diameter at the top than at the bottom.

it is an upright frame made fast to the ends of the rail S. Attached to said frame is a series of curved braces Z, which are slotted at if, their lower ends being made fast to the head end of the formers.

A series of angular clamping -bars B is shown in Fig. 1. Said clamping-bars pass through the slots 75 of the braces Z, and have their rear ends pivoted at e to the rail 3 of the traveling frame. A coiled spring f is attached to each of the clamping-bars at 0.", having their opposite ends made fast to the upright frame at at a. The portion of the clam ping-bars projecting from the braces Z is so bent-or shaped that when the bar is in a horizontal position, as shown in Fig. 2, it will lie on an angle coinciding with the inclined face of the former F, as shown at 2 in Fig. 2. The free end of each clamping-bar is provided with the hook e, which engages with the spring clamp or catch a, mounted on the outer end of the former F, as shown clearly in Fig. 2. By this arrangement the clampingbar is held firmly in its horizontal position, the object of which will be hereinafter explained. The clamping-bar is released by pressing inward on the spring-catch a, at which time the coiled spring f will raise the clamping-bar to the position shown at the left of Fig. 1, the clamping-bar in its movements traveling in the slot t of the curved brace.

Each clamping-bar is provided on the under face with a pin or needle 2', which, when the clamping-bar islocked, as shown in Fig. 2, passes through the lap y of the paper blank B, as shown in Fig. 2, striking the button Z in the body of the former F, forcing the auxiliary needle or pin 4." within the former F out through the paper blank at a point directly opposite from where the needle 1' passed I00 through, thereby forming the holes (3" through the body of the vessel, which holes receive the ends of the bail h of the vessel, as shown in Fig. 6. When the clamping-bar B is raised by the springf, the pin or needle i draws out of the body of the vessel or blank B. At the same time the spring tr in the body of the former F' forces the needle i" back into the former, when the vessel-body P, formed there-.

on, may be readily removed.

In Fig. 5, F shows a former in an upright position, having a stand \V and base-support D. ()n this former the bottom I) of the vessel is placed, said bottom being cut round and of a diameter greater than that of the vesselbody. The body'of the vessel is then inverted and forced down over this former, pressing the bottom D tightly into the tapering body, which is then removed. The bail h is then attached and the vessel is completed, as shown in Fig. 6.

Having described the invention, the operations are as follows: The sheet of paper or blank which forms the body of the vessel is shown in Fig. 4. This blank B is by the operator folded around one of the formers F of the traveling frame, beginning at one end of the frame. The blank is out large enough to pass around the former and lap at 3 at which point the paper blank is coated with a suitable adhesive agent. Thelap being closed, the operator brings down one of the clampingbars B, and looking it, as before stated, the frame is then moved along or to the right, when the operator in alike manner applies a blank B around the next former F, andlocks the clamping-bar B, and so on until the series of formers are covered, when the operator moves the carriage back to the left. Then, by releasing the catch a, the clamping-bar B by the springf will rise, when the body I of the vessel may be removed from the former. The cement or adhesive agent having set holds the parts. A paper disk is then placed on the upper end of the former F of Fig. 5, and the vessel-body P is inverted and forced down on said former, thereby pressing the bottom or disk D sufliciently tight into the body of the vessel to hold it in position. The bail 7t being hooked into the holes at the top of the vessel, the pail is completed.

I use for the bottom D a grade, of heavier paper than that used in forming the body of the vessel, and I design in some cases to cement or coat the inner face of the vessel with an impervious cement, so as to enable it to hold liquids.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device for the purposes specified, the combination, with the supporting-frame carrying a series of tapering formers, which formers project horizon ally therefrom, of the series of clamping-bars, their free ends engaging with the outer ends of the formers, their rear ends being pivoted to the supportin g-frame, and the series of springs for raising said clamping-bars, substantially as and for the purposes specified.

2. In combination with the platform, the traveling frame mounted thereon, and having the series of horizontally-projecting formers, the series of slotted braces, the clamping-bars having a hook at one end to engage with the outer ends of the formers, their inner ends being pivoted to the traveling frame, and a spring for raising each clamping-bar, substantially as specified.

In a paper-vessel-making machine, the combination, with the former mounted on the horizontal support, and having the needle within said former with actuating-spring, of

the angular clamping-bar pivoted at one end, its opposite end adapted to engage with the outerend of the former, and the needle carried by the clamping-bar, which needle actuates the needle within the former, as and for the purposes specified.

4. The combination of the support S, the former mounted thereon, the needle, button, and spring located in said former, the springcatch, the clamping-bar pivoted at one end, its opposite end having a hook to engage with the spring-catch on the outerend of the former, the needle attached to the under face of the clamping-bar, and a spring for raising said clamping-bar, substantially as and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.

FRED. ELWELL.
